Justipedia explains Maritime Lien
In its most dramatic form, a maritime lien allows a sailor to demand that the ship that the sailor worked on be sold and the profits shared with the sailor if the ship’s owner fails to pay the sailor.
The concept of a maritime lien originates in old English common law, when ship owners were notorious for promising riches and adventure to entice poor people to work on their ships. When these ventures failed, sailors were often left destitute. So, maritime liens developed to help sailors be paid for their services.
